DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0047] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0049] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the inventive product is usually placed when in use, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0050] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] This embodiment provides an unmanned device, which includes a mobile device and a spreading mechanism 010 (such as Figure 1 As shown), the mobile device can drive the sowing mechanism 010 to move synchronously, so as to utilize the sowing mechanism 010 to sow materials such as seeds or fertilizers.

[0052] The mobile device can be selected as needed, for example, it can be: a drone, an unmanned vehicle or a robot, etc., which is not specifically limited here.

[0053] It should be understood that in other embodiments, the spreading mechanism 010 can also be carried by workers to move and complete the spreading operation, which is not specifically limited here.

[0054] Please refer to Figure 1 and Figure 2 The spreading mechanism 010 includes a frame 100 and a spinning disc 200. The spinning disc 200 is rotatably disposed on the frame 100 so that when the spinning disc 200 rotates, the material is knocked out to complete the spreading operation.

[0055] For further information, please refer to Figure 2The spinner 200 includes a spinner body 210, a first blade 220 and a second blade 230. The spinner body 210 is rotatably connected to the frame 100 and is configured to rotate in a plane that is at an angle to the horizontal plane. The first blade 220 and the second blade 230 are both arranged on the spinner body 210, and the second blade 230 is closer to the rotation center of the spinner body 210 relative to the first blade 220. When the spreading mechanism 010 is used to spread the material, the spinner body 210 rotates relative to the frame 100, and drives the first blade 220 and the second blade 230 to rotate synchronously. On the one hand, the first blade 220, which is far from the rotation center of the spinner body 210, can be used to directly hit and spread a part of the material, and the second blade 230, which is located near the rotation center of the spinner body 210, can be used to hit the other part of the material to the outer ring of the spinner body 210, and then the first blade 220 will beat the material moved to the outer ring of the spinner body 210, so that the material can be effectively spread to a position close to the spinner 200 and a position far from the spinner 200. The second blade 230 can knock out the material missed by the first blade 220, and the first blade 220 complements the second blade 230 to spread the material evenly; on the other hand, the disc body 210 rotates in a plane that is at an angle to the horizontal plane, so that the material feeding speed when the material is transported to the disc 200 for spreading reduces the influence of the material spreading width, thereby making the spreading width of the material spread by the disc 200 more constant; since the material can be effectively hit and spread to a position close to the disc 200 and a position far away from the disc 200, and the spreading width of the spread material is relatively constant, it can effectively improve the problem of easy missing or repeated broadcasting, thereby improving the uniformity of material spreading.

[0056] The spreading disc of the spreading device provided by the related art rotates in a horizontal plane. As the speed of material feeding and conveying to the spreading disc changes, the spreading width of the material spread by the spreading disc changes accordingly, which easily causes re-seeding or missed seeding in the working area, resulting in uneven material spreading. The disc body 210 of this embodiment rotates in a non-horizontal plane, that is, in a plane at an angle to the horizontal plane, which can reduce the influence of the feeding speed on the spreading width of the material, thereby improving the problem of re-seeding or missed seeding and uneven material spreading.

[0057] In this embodiment, the spinner body 210 is configured to rotate in a vertical plane, that is, the rotation axis of the spinner body 210 extends in the horizontal direction, so as to fully improve the influence of the material discharge speed on the sowing width, so that the sowing width of the spinner 200 when sowing materials is constant, improve the uniformity of material sowing, thereby ensuring efficient sowing operations, and is conducive to increasing the yield of crop production.

[0058] The structure of the first blade 220 can be selected as needed, please continue to refer to Figure 2The first blade 220 of this embodiment includes a first plate 221 and a second plate 222 connected in sequence, wherein the second plate 222 is closer to the rotation center of the spinner body 210 relative to the first plate 221, and along the extension direction of the rotation axis of the spinner body 210, the height of the second plate 222 is less than the height of the first plate 221. In this way, when spreading materials, the relatively short second plate 222 can be used to knock down the materials near the rotation center of the spinner body 210, so as to speed up the flow speed of the materials, ensure efficient material spreading, and effectively improve the problem of easy accumulation of materials when the materials are transported to the position near the rotation center of the spinner body 210.

[0059] Furthermore, the first plate 221 and the second plate 222 extend in the same direction, that is, the first plate 221 and the second plate 222 are connected at a right angle, that is, the angle between the first plate 221 and the second plate 222 is 180°; in this way, the first blade 220 is roughly L-shaped, which can ensure that the first blade 220 can reliably hit the material, so that the material can be efficiently spread.

[0060] It should be understood that in other embodiments, the first plate 221 and the second plate 222 may also be spaced apart from each other on the spinner body 210 .

[0061] In other embodiments, the angle between the first plate 221 and the second plate 222 may also be 179°, 177°, etc., which is not specifically limited here.

[0062] Please refer to Figure 3 In this embodiment, the length extension direction of the first blade 220 is distributed at an angle α with the diameter of the spinner body 210; so that when the spinner body 210 drives the first blade 220 to rotate synchronously, the first blade 220 can be used to effectively and reliably hit the material, thereby allowing the material to be stably and reliably spread out.

[0063] The spinning disc 200 includes a plurality of first blades 220 , which are spaced apart in sequence around the rotation center of the spinning disc body 210 ; the plurality of first blades 220 can efficiently and stably beat and spread the materials.

[0064] Furthermore, the angle α between the plurality of first blades 220 and the diameter of the spinner body 210 gradually increases along the preset direction a, and the spinner body 210 is configured to rotate along the preset direction. In this way, when the material is hit by the first blade 220 having a large angle with the diameter, it can fall to the area directly below the spinner body 210 or the area close to the area directly below the spinner body 210, and when the material is hit by the first blade 220 having a small angle with the diameter, it can fall to the area far from the spinner body 210, which is conducive to making the material more evenly spread.

[0065] Furthermore, the lengths of the projections C of the first plates 221 of the multiple first blades 220 on the diameter of the spinner body 210 are all equal; this is beneficial for ensuring that the material is struck by approximately the same force from each of the first plates 221, thereby improving the uniformity of material spreading; in particular, when the heights of the first plates 221 of each of the first blades 220 are consistent along the extension direction of the rotation axis of the spinner body 210, the projected areas of the material struck by the first plates 221 can be the same, and the material is struck with approximately the same force, which is beneficial for ensuring uniform spreading of the material.

[0066] Of course, in other embodiments, the angles between each first blade 220 and the diameter of the spinner body 210 may be the same; or, along a preset direction, the angles between the plurality of first blades 220 and the diameter of the spinner body 210 may be alternately arranged in sequence or randomly arranged according to at least two different angles, etc., which are not specifically limited here.

[0067] In other embodiments, the projected lengths of the first plates 221 of the first blades 220 on the diameter of the spinner body 210 may be different.

[0068] It should be noted that the lengths of the second plates 222 of the first blades 220 may be the same. Of course, in other embodiments, the lengths of the second plates 222 of the first blades 220 may be different or the same; and in some embodiments, the lengths of the projections of the second plates 222 of the plurality of first blades 220 on the diameter of the spinner body 210 may be equal, which is not specifically limited here.

[0069] Please refer to Figure 2 In this embodiment, along the extension direction of the rotation axis of the spinner body 210, the height of the second blade 230 is less than the height of the first plate 221, and greater than the height of the second plate 222. In this way, the second blade 230 can be used to effectively hit the material to the outer ring of the spinner body 210, and then the first blade 220 distributed on the outer ring of the spinner body 210 hits the material to make up for the material density in the area directly below the spinner body 210, thereby improving the uniformity of material spreading; the second blade 230 can also be effectively used to improve the problem that the material is easily accumulated at a position close to the rotation center of the spinner body 210.

[0070] Please refer to Figure 2 and Figure 3 Furthermore, the length of the second blade 230 extends along the diameter of the spinner body 210; this is beneficial for effectively hitting the material to the outer ring of the spinner body 210, thereby improving the uniformity of material spreading.

[0071] Of course, in other embodiments, the length extension direction of the second blade 230 may also form an angle of 3°, 5°, etc. with the diameter of the spinner body 210, which is not specifically limited here.

[0072] Optionally, the length of the second blade 230 is smaller than the length of the second plate 222, so as to ensure that the first blade 220 and the second blade 230 can reliably hit and spread the material without interfering with each other in hitting and spreading the material.

[0073] The number of the second blades 230 can be selected as needed. In this embodiment, the spinner body 210 is provided with two second blades 230, which are mirror-distributed. In other embodiments, the number of the second blades 230 can also be one, three, four, etc., which is not specifically limited here.

[0074] It should be understood that in some embodiments, please refer to Figure 4 Any second blade 230 is located between two adjacent first blades 220. In this way, the second blade 230 can be used to reliably hit the material missed by the first blade 220, so that the first blade 220 and the second blade 230 can form a reliable complement to ensure the uniformity of material spreading.

[0075] In some embodiments, at least two adjacent first blades 220 have different angles with the diameter of the spinner body 210. Figure 4 As shown, the angles a1 and a2 between two adjacent first blades 220 and the diameter of the spinner body 210 are different. It should be understood that the different angles between at least two adjacent first blades 220 and the diameter of the spinner body 210 may mean that the angles between all the first blades 220 and the diameter of the spinner body 210 are different, or as long as there are two adjacent first blades 220 and the diameter of the spinner body 210 The angle is different. This arrangement allows the first blades 220 to be arranged at more angles, achieving multi-angle spreading of materials and improving the problem of uneven material spreading in the prior art.

[0076] It should be noted that the angle between the diameter of the first blade 220 and the spinner body 210 refers to the angle between the diameter of the end of the first blade 220 close to the center of the spinner body 210 and the length extension direction of the first blade 220; or, it can be Figure 5 As shown, the angle between the diameter of the end of the first blade 220 away from the center of the spinning tray body 210 and the length extension direction of the first blade 220 is included.

[0077] In some embodiments, at least two adjacent second blades 230 have different angles with the diameter of the spinner body 210. Figure 4As shown, the angles b1 and b2 between two adjacent second blades 230 and the diameter of the disk body 210 are different. It should be understood that the different angles between at least two adjacent second blades 230 and the diameter of the disk body 210 may mean that the angles between all the second blades 230 and the diameter of the disk body 210 are different, or as long as there are two adjacent second blades 230 and the angles between the diameter of the disk body 210 are different. Such an arrangement allows the second blades 230 to have more angles, realize multi-angle spreading of materials, and improve the problem of uneven material spreading in the prior art. It should be noted that the angle between the second blade 230 and the diameter of the disk body 210 is similar to the angle between the first blade 220 and the diameter of the disk body 210, which will not be repeated here.

[0078] In some embodiments, the length of the second blade 230 is less than the length of the first blade 220. In this way, the second blade 230 can fully compensate for the impact of the first blade 220 on the material without interfering with the impact of the first blade 220 on the material.

[0079] In some embodiments, Figure 6 As shown, the angle c between the second blade 230 and the adjacent first blade 220 is 0-90°; the angle c between the second blade 230 and the adjacent first blade 220 may refer to the angle between the length extension direction of the second blade 230 and the length extension direction of the adjacent first blade 220. Further, the angle between any adjacent first blade 220 and second blade 230 only needs to be 0-90°, so that the first blade 220 and the second blade 230 can have a variety of different arrangements, thereby realizing multi-angle spreading of materials and improving the problem of uneven material spreading in the prior art.

[0080] In some embodiments, at least two angles formed by adjacent first blades 220 and second blades 230 are different. Figure 6 As shown, the angle of the angle c between one pair of adjacent first blades 220 and the second blade 230 is different from the angle of the angle c' between another pair of adjacent first blades 220 and the second blade 230. In this way, the first blades 220 and the second blade 230 can have a variety of different arrangements, thereby achieving multi-angle spreading of materials and improving the problem of uneven material spreading in the prior art. In some embodiments, it can also be set that the angles formed by any two adjacent first blades 220 and the second blade 230 are different. In some embodiments, the angle c between one pair of adjacent first blades 220 and the second blade 230 is different from the angle of the angle c' between another pair of adjacent first blades 220 and the second blade 230.

[0081] The spreading mechanism 010 of this embodiment further comprises a motor 300 , and the output shaft of the motor 300 is transmission-connected to the spinning disc 200 to drive the spinning disc 200 to rotate.

[0082] Please refer to Figure 2 The spinner 200 further includes a connecting member 240, which is connected to the spinner body 210; specifically, the connecting member 240, the first blade 220 and the second blade 230 are connected to the same side of the spinner body 210; the output shaft of the motor 300 is transmission-connected to the connecting member 240 to drive the connecting member 240 to drive the spinner body 210 to rotate.

[0083] The connecting member 240 of this embodiment is a cylinder; in other embodiments, the connecting member 240 may also be a prism, etc., which is not specifically limited here.

[0084] The transmission connection mode between the connecting member 240 and the output shaft of the motor 300 can be selected as required. Figure 7 and Figure 8 In this embodiment, the spinner body 210 is provided with a mounting hole 211, which is provided on a side of the spinner body 210 away from the connecting piece 240 and extends to the connecting piece 240. The output shaft of the motor 300 is inserted into the mounting hole 211 to be connected to the spinner body 210 and the connecting piece 240 at the same time, thereby being able to reliably drive the spinner body 210 to rotate.

[0085] It should be understood that in other embodiments, the connecting piece 240 is not provided on the spinner body 210 , and the output shaft of the motor 300 is only connected to the spinner body 210 .

[0086] For further information, please refer to Figure 2 The spinner body 210 is also provided with a fixing hole 212, which is used to set fasteners such as bolts or screws, so that the fasteners set in the fixing hole 212 are fixedly connected to the output shaft of the motor 300, thereby ensuring the stability of the connection between the output shaft of the motor 300 and the spinner body 210.

[0087] Optionally, in some embodiments, the output shaft of the motor 300 is inserted into the mounting hole 211 and may also be threadedly connected to the inner wall to ensure stability and ease of disassembly between the output shaft of the motor 300 and the connector 240 .

[0088] Please refer to Fig. 9 and Fig.10The frame 100 of this embodiment includes a material guide tube 110 and a cover plate 120. The material guide tube 110 is connected to the cover plate 120. The two ends of the material guide tube 110 are respectively provided with an inlet 111 and an outlet 112. The spinner body 210 is rotatably connected to the cover plate 120, and the outlet 112 is opposite to the side of the spinner body 210 where the first blade 220 and the second blade 230 are provided. In this way, the material to be spread can enter the material guide tube 110 from the inlet 111, and then move to the outlet 112 under the guidance of the material guide tube 110, and move to the space between the cover plate 120 and the spinner body 210, and then can be effectively hit by the first blade 220 and the second blade 230 to complete the spreading operation.

[0089] It should be understood that in other embodiments, the motor 300 is disposed on the cover plate 120 , that is, the motor 300 is disposed on a side close to the discharge port 112 , which is conducive to making the structure more compact.

[0090] It should be noted that the unmanned equipment also includes a storage mechanism, which is arranged on the mobile device, and is used to store materials to be spread, and can transport the materials into the material guide pipe 110 through the feed inlet 111 of the material guide pipe 110. Furthermore, the structure and working principle of the storage device are similar to those of the related art, and will not be repeated here.

[0091] The structure of the guide tube 110 can be selected as needed, please continue to refer to Fig. 9 The material guide pipe 110 of this embodiment includes a first pipe 113 and a second pipe 114 which are interconnected, and the first pipe 113 and the second pipe 114 are respectively connected to the two sides of the cover plate 120, and the end of the first pipe 113 away from the second pipe 114 is provided with a material inlet 111, and the end of the second pipe 114 away from the first pipe 113 is provided with a material outlet 112. In this way, the second pipe 114 protrudes relative to the cover plate 120 and extends between the spinner body 210 and the cover plate 120, so that the material can slide more reliably to cooperate with the spinner 200, and then the first blade 220 and the second blade 230 can reliably hit the material.

[0092] In order to allow all the materials entering the material guide tube 110 to move between the spinner plate 200 and the cover plate 120, the connection between the inner tube wall of the first tube 113 and the inner tube wall of the second tube 114 is smoothly transitioned to prevent the materials from being blocked in the material guide tube 110 and unable to be discharged.

[0093] Please refer to Fig. 9 and Fig.10The material guide pipe 110 of this embodiment is a reducer; specifically, the inner diameter of the material guide pipe 110 gradually decreases from the material inlet 111 to the material outlet 112; in this way, the materials passing through the material guide pipe 110 can be transported to between the cover plate 120 and the spinner 200 in a concentrated manner, thereby efficiently striking the materials and ensuring the spreading efficiency.

[0094] Optionally, the guide pipe 110 is a curved pipe, so that the pipe wall of the guide pipe 110 can be used to guide the movement of the material, and the material can quickly slide out of the guide pipe 110, thereby ensuring the material spreading efficiency. Of course, in other embodiments, the guide pipe 110 can also be a straight pipe, which is not specifically limited here.

[0095] Please combine Fig. 9 and Fig.10 In order to enable the first blade 220 and the second blade 230 to fully hit the material, the discharge port 112 is distributed on one side of the rotation axis of the spinner body 210 and can be opposite to the second blade 230. In this way, when the spreading mechanism 010 is used, the discharge port 112 can be distributed on the upper half of the spinner body 210 relative to the spinner body 210 to ensure that the material output from the discharge port 112 can be fully hit by the first blade 220 and the second blade 230.

[0096] Optionally, the discharge port 112 is distributed obliquely above the spinner body 210 , for example, the discharge port 112 is distributed at the upper right or upper left relative to the spinner body 210 to further ensure that the material can be fully hit by the first blade 220 and the second blade 230 .

[0097] It should be noted that the discharge port 112 being able to be opposite to the second blade 230 may mean that: the discharge port 112 can be able to be opposite to at least one second blade 230, so that the second blade 230 can be used to reliably hit the material output from the discharge port 112 onto the outer ring of the spinner body 210, thereby ensuring uniform and efficient material spreading.

[0098] Please refer to Fig. 9 and Fig.10 The frame 100 of this embodiment further includes a shielding member 130, which is fixedly connected to the cover plate 120, and the discharge port 112 is distributed between the shielding member 130 and the rotation axis of the spinner body 210. In this way, the material can be reliably spread out from the spinner body 210 away from the shielding member 130, thereby ensuring the reliability of material spreading. When the spreading mechanism 010 is in use, the discharge port 112 is distributed obliquely above the spinner body 210, and the discharge port 112 is located between the shielding member 130 and the rotation axis of the spinner body 210, so that the shielding member 130 blocks the top of the spinner 200, so that the material can be reliably spread out from below and obliquely below after being hit by the spinner 200.

[0099] Furthermore, the side wall of the shielding member 130 facing the spinner body 210 is arc-shaped and extends along the rotation direction of the spinner body 210. In this way, the assembly gap between the shielding member 130 and the spinner body 210 can be reduced, which is conducive to miniaturization and compact structural design.

[0100] Furthermore, the shielding member 130 is a curved plate to ensure that the shielding member 130 occupies a smaller space, which is conducive to realizing a miniaturized design.

[0101] Of course, in other embodiments, the shielding member 130 only needs to have a side wall opposite to the spinner body 210 in an arc shape, which is not specifically limited here.

[0102] Please refer to Fig.10 The frame 100 further includes a fixing frame 140, the shielding member 130 is connected to the fixing frame 140, and the fixing frame 140 is used to be assembled on the mobile device; in this way, the spreading mechanism 010 can be assembled on the mobile device.

[0103] The connection method between the fixing frame 140 and the shielding member 130 can be selected as needed. The fixing frame 140 and the shielding member 130 of this embodiment are clamped together. Through the clamping connection between the fixing frame 140 and the shielding member 130, when the motor 300 drives the spinning disc 200 to rotate, it is ensured that only the spinning disc 200 rotates, and the cover plate 120 and the shielding member 130 can stay in the assembly position stably and reliably, thereby ensuring the reliability of the spinning disc 200 in hitting and spreading materials.

[0104] Of course, in other embodiments, the fixing frame 140 and the shielding member 130 may also be connected by welding, by fasteners such as bolts, etc., which is not specifically limited here.

[0105] In this embodiment, the connecting member 240 is rotatably connected to the cover plate 120. Thus, when the motor 300 drives the spinning disc 200 to rotate, the stability of the spinning disc 200 can be ensured, thereby reliably and stably spreading the material.

[0106] Please refer to Figure 8 and Fig. 9 The cover plate 120 is provided with a plug-in column 121 , and the end of the connecting member 240 away from the spinner body 210 is provided with a plug-in hole. The plug-in column 121 is rotatably plugged into the plug-in hole to ensure that the spinner body 210 can rotate reliably under the drive of the motor 300 .

[0107] In other embodiments, the cover plate 120 is provided with a through hole, and one end of the connecting member 240 away from the spinner body 210 is rotatably plugged into and fitted with the through hole.

[0108] Please refer to Figure 8The spreading mechanism 010 also includes a fixing member 150, which can be connected to the cover plate 120, the connecting member 240, the spinner body 210 and the output shaft of the motor 300 in sequence, that is, the fixing member 150 passes through the cover plate 120, the connecting member 240, the spinner body 210 in sequence and is connected to the output shaft of the motor 300; in this way, the cover plate 120, the spinner 200 and the output shaft of the motor 300 can be stably assembled together, and it can be ensured that the output shaft of the motor 300 can drive the spinner 200 to rotate stably.

[0109] Furthermore, the fixing member 150 passes through the cover plate 120, the connecting member 240, and the spinneret body 210 in sequence and is threadedly connected to the output shaft of the motor 300 to ensure that the fixing member 150 is stably connected to the output shaft of the motor 300, so that the output shaft of the motor 300 can reliably drive the spinneret body 210 to rotate.

[0110] Optionally, the fixing member 150 can also be threadedly connected to the connecting member 240 to further ensure the stable connection between the spinner 200 and the output shaft of the motor 300 through the fixing member 150, thereby ensuring that the motor 300 can drive the spinner 200 to rotate reliably.

[0111] It should be understood that in other embodiments, the fixing member 150 can also be tightly plug-fitted, or snap-fitted, etc. with the output shaft of the motor 300 and at least one of the connecting member 240 .

[0112] Please note that, please refer to Figure 8 The fixing member 150 may include a head 151, an optical axis portion 152 and a threaded portion 153 connected in sequence. When the fixing member 150 is sequentially plugged into the cover plate 120, the connector 240, the spinner body 210 and the output shaft of the motor 300, the head 151 is distributed on the side of the cover plate 120 away from the spinner 200, the optical axis portion 152 is plugged into the plug-in column 121, and the threaded portion 153 is threadedly connected to the output shaft of the motor 300. Of course, in some embodiments, the threaded portion 153 may also be threadedly connected to the connector 240.

[0113] It should also be noted that, in order to further ensure that the motor 300 reliably drives the spinning tray 200 to rotate, the motor 300 can be fixedly disposed on the fixing frame 140. Of course, in other embodiments, the motor 300 can also be disposed on a mobile device, which is not specifically limited here.

[0114] Please continue to refer to Figure 8 The spreading mechanism 010 of this embodiment further includes a first bearing 161, which is disposed between the plug-in column 121 and the hole wall of the plug-in hole, so as to utilize the first bearing 161 to ensure that the spinner 200 rotates stably and smoothly.

[0115] Furthermore, the spreading mechanism 010 also includes a second bearing 162. A bearing hole 122 is provided on the side of the cover plate 120 away from the spinner 200. The second bearing 162 is arranged in the bearing hole 122 and is sleeved on the fixing member 150 to ensure that the fixing member 150 can rotate smoothly and stably synchronously with the spinner 200 relative to the cover plate 120, thereby ensuring the smooth and stable rotation of the spinner 200.

[0116] In this embodiment, the cover plate 120, the connecting member 240, the spinner body 210 and the first blade 220 can form a receiving space for receiving the material to be spread; specifically, the receiving space is roughly distributed above the spinner body 210. In this way, it is convenient to control the discharge angle when spreading the material, so as to achieve uniform material spreading.

[0117] The number of spreading mechanisms 010 set up in the unmanned equipment can be selected as needed, please refer to Fig.11 The unmanned equipment of this embodiment includes two spreading mechanisms 010, and the two spreading mechanisms 010 are symmetrically distributed, and the swinging discs 200 of the two spreading mechanisms 010 rotate in two opposite directions, that is, the swinging disc 200 of one spreading mechanism 010 rotates clockwise, and the swinging disc 200 of the other spreading mechanism 010 rotates counterclockwise; in this way, not only the efficiency of material spreading can be improved, but also the spreading uniformity can be ensured, the working efficiency can be improved, and the working cost can be reduced.

[0118] The unmanned equipment of this embodiment can use the spreading mechanism 010 to spread seeds, fertilizers, etc. The spreading principle of the spreading mechanism 010 includes: the material to be spread is transported to the spinner 200 through the material guide pipe 110, and the first blade 220 and the second blade 230 on the spinner body 210 hit the material so that the material is spread out.

[0119] In summary, when the spreading mechanism 010 of the present invention spreads materials, on the one hand, it can use the first blade 220 that is far from the rotation center of the spinner body 210 to directly hit and spread a part of the materials, and use the second blade 230 located near the rotation center of the spinner body 210 to hit the other part of the materials to the outer ring of the spinner body 210, and then the first blade 220 will beat the materials moved to the outer ring of the spinner body 210, so that the materials can be effectively spread to the position close to the spinner 200 and far away from the spinner body 210. On the one hand, the spinning disc 200 is positioned, and on the other hand, the spinning disc body 210 rotates in a plane that is at an angle to the horizontal plane, so that the feeding speed of the material when it is transported to the spinning disc 200 for sowing reduces the influence of the material sowing width on the material sowing, thereby making the sowing width of the material sown by the spinning disc 200 more constant; since the material can be effectively struck and sown to a position close to the spinning disc 200 and a position far away from the spinning disc 200, and the sowing width of the sowing material is more constant, it can effectively improve the problem of easy omission or re-seeding, thereby improving the uniformity of material sowing.

[0120] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
